Strength of Materials - April 15, 2015

These are the pictures from the project I did in the fall. Again, because I had to load the books carefully, and the structures did collapse, I don't have "action" pictures. But these are some of the examples of the support structure the students from 2nd - 5th grades built.PreviousSupplies List:
25 straws (Dollar Store variety)
6 bamboo chopsticks (3 pairs)
scotch tape

I couldn't get my hands on the same, stronger bamboo chopsticks, so I had to settle for either thinner, weaker bamboo chopsticks or regular wooden ones. I bought both types, but they didn't quite hold up. Still, it doesn't make this project any less fun to do.

Project Instructions:

Hand out 25 straws and 6 chopsticks to each team of students.

Talk about load distribution.

Build and test.

Get more material (another pair of chopsticks or 5 straws) and make repairs. And test again.
